“…In such cases, a breeding strategy which would enable to utilize maximum proportion of fixable genetic variation (additive and additive×additive epistasis) as well as non additive genetic components (dominance, additive×dominance and dominance×dominance) would be effective. Similar findings were reported by Gupta et al, (2010). Higher magnitude of gca component (g i 2 ) than sca component (s ij 2 ) was observed for siliqua length in timely sown condition, indicating that this trait was mainly under the control of additive genetic variance.…”

IntroductionIndian mustard (Brassica juncea) is a naturally autogamous species, yet in this crop frequent out-crossing occur which varies from 5 to 30% depending upon the environmental conditions and random variation of pollinating insects. Cytologically Indian mustard is an amphidiploid (2n=36), derived from interspecific cross of Brassica campestris (2n=20) and Brassica nigra (2n=16) followed by natural chromosome doubling. These relationships have been confirmed by the artificial synthesis of amphidiploids species by hybridizing basic diploid species and also by analysis of chloroplast and mitochondrial DNA restriction pattern of basic and amphidiploids International Journal of Current Microbiology and Applied Sciences ISSN: 2319-7706 Volume 6 Number 5 (2017) pp. 942-953Journal homepage: http://www.ijcmas.comHalf diallel analysis of eight parents was carried out to identify the high heterotic crosses and their relationship in terms of general and specific combining ability (gca & sca) in Brassica juncea L. Czern and Coss. Mean squares due to parent v/s crosses were also significant for all the traits which depicted presence of heterosis for all the traits, except for days to maturity, plant height, siliquae on main shoot, number of seeds/siliqua, siliqua length and oil content in timely sown condition and for plant height, number of primary branches per plant, siliqua on main shoot and 1000 seed weight in late sown condition. The heritability in narrow-sense showed the prevalence of additive variance for siliqua length, days to maturity, number of primary branches per plant in late sown condition, while for other traits an appreciable proportion of total variance was non-additive in both the environments. In the present study, an overall appraisal of GCA effects revealed that RH0735 and BPR349-9 in normal environment and RH0116 and RH0555A in late sown environment were good general combiner for majority of the characters. High GCA effects are related to additive gene effects or additive x additive interaction which represent the fixable genetic component of variation. Hence these parents could be efficiently used for exploiting seed yield. For seed yield the crosses RH8814 x RH0555A, RH0644 x BPR543-3 and BPR349-9 x RH0644 in timely sown condition and crosses RH0555A x RH0644, RH0735 x RH0116 and BPR349-9 x RH0644 were identified as promising on the basis of their high per se performance and with high significant SCA effects. These crosses could be extensively used in breeding programme to develop superior segregants and the parents involved may be converted to well adapted cytoplasmic male sterile or restorer lines in further breeding programmes.

“…cluster analysis and principal component analysis (PCA). These techniques were successfully observed in Indian mustard (Brassica juncea L.) germplasm by Gupta et al [21], in Ethiopian mustard by Alemayehu and Becker [16] and in white head cabbage Balkaya et al [22]. All the above mentioned plant breeders and plant scientist's results gives support to our present investigation that these 2 techniques are very supportive in estimated associations among individuals originated from different environments in a more clear approach.…”

Indian mustard (Brassica juncea L.) germplasm consisting 167 accessions including one check cultivar was evaluated for qualitative and quantitative traits. The present study was conducted to investigate genetic diversity and correlation among studied genotypes of B. juncea L. based on agro-morphological at NARC, Islamabad, Pakistan. To investigate the genetic diversity based on morphological characters, data was recorded on 20 quantitative and 12 qualitative traits. The calculated data was analyzed through two complementary methods, i.e. PCA (Principal Component Analysis) and cluster analysis. Among all the studied cultivars, significant diversity was recorded for different agro-morphological characters. Among all the parameters, maximum variance was recorded for pod shattering (427.2) followed by plant height (345.6), days to 100% flowering (336.2) and main raceme length (210.0). Among all the characters, the greatest and highly significant association (0.99) was found between days to maturity 50% and days to maturity 100% followed by correlation (0.86) among days to flowering 50% and days to flowering 100%, correlation value (0.71) was calculated among leaf length and leaf width. Using cluster analysis all the genotypes were divided into five major groups. It was observed that 7 out of 20 principal components with an Eigen value of ≥1.0 calculated for 73.92% of the total diversity observed between 167 accessions of Indian mustard (B. juncea L.). The contribution of first three PCs in the total PCs was 23.25, 12.87 and 11.24, respectively. Among all the investigated accessions two genotypes 26,813 and 26,817 showed great How to cite this paper: Saleem, N., Jan, S.A., Atif, M.J., Khurshid, H., Khan, S.A., Abdullah, M., Jahanzaib, M., Ahmed, H., Ullah, S.F., Iqbal, A., Naqi, S., Ilyas, M. 70potential for seeds/silique, 1000-seed weight and seed yield/plant, respectively, so these genotypes are recommended for future breeding programs for achieving promising results.

The study was conducted to evaluate five female parents (lines) and eight male parents (testers) in a line x tester mating design at the research field of Sher-e-Bangla Agricultural University, Bangladesh, to estimate their gene action and heterosis for seed yield and yield contributing attributes in rapeseed. The data recorded on 40 F1's and their parents for their combining ability indicated that the GCA effect was significant for primary branches per plant, secondary branches per plant, number of siliqua per plant, seeds per siliqua, thousand seed weight and seed yield per plant. High ratio of GCA and SCA variance was observed indicating a preponderance of non-additive gene effects in the inheritance of the yield and yield contributing characters under study. Among the lines Nap 9908 and Nap 94006 were found as good general combiners. Among 40 hybrids 16 were found as a good specific combiner for yield and yield contributing characters. Different types of heterosis, i.e. heterosis over mid parent (Hm), heterosis over better parent (Hb) and heterosis over the standard check (Hc) were estimated to evaluate forty hybrids for seed yield and yield contributing characters. The average heterosis for seed yield of forty hybrids over mid parent was 3.27% and that of better parent and the standard check was -9.72% and 5.60%, respectively.
